Gcgr Gene Summary [Mouse]
Enables glucagon receptor activity. Involved in several processes, including cellular response to glucagon stimulus; glucose homeostasis; and regulation of glycogen metabolic process. Acts upstream of or within cellular response to starvation and positive regulation of gene expression. Is active in plasma membrane. Is expressed in several structures, including brain; foot mesenchyme; gut; liver; and male reproductive gland or organ. Used to study Mahvash Disease. Human ortholog(s) of this gene implicated in Mahvash Disease and type 2 diabetes mellitus. Orthologous to human GCGR (glucagon receptor). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Gcgr often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
